PHP code for adding a calendar to your blog

Do you want to add a calendar to your blog? blue1000 is here to briefly share with you a blog calendar implementation code in PHP. Friends in need can refer to it. There is a sentence in it that querying the database is very simple. You only need to modify the field name to be the same as your database.

The code is as follows:

Function calendarnew($starttime = 0) {

global $db, $tablepre, $timestamp, $site_timeoffset, $site_dateformat, $curtime;

　$starttime = $starttime ? $starttime : $timestamp;

$curtime = gmdate($site_dateformat, $starttime + $timeoffset * 3600);

　$pendtime = $starttime - (gmdate('j', $starttime + $timeoffset * 3600) - 1) * 86400 - ($starttime + $timeoffset * 3600) % 86400;

　$pstarttime = $pendtime - gmdate('t', $pendtime + $timeoffset * 3600 - 1) * 86400;

　$nstarttime = $pendtime + gmdate('t', $pendtime + $timeoffset * 3600 + 1) * 86400;

　$nendtime = $nstarttime + gmdate('t', $nstarttime + $timeoffset * 3600 + 1) * 86400;

List($skip, $dim) = explode('-', gmdate('w-t', $pendtime + $timeoffset * 3600 + 1));

　$rows = ceil(($skip + $dim) / 7);

　$blogs = array();

$query = $db->query("SELECT dateline FROM {$tablepre}vitaitems WHERE dateline BETWEEN '$pendtime' AND '$nstarttime'");

while($blog = $db->fetch_array($query)) {

　$day = gmdate('j', $blog['dateline'] + $timeoffset * 3600);

　!isset($blogs[$day]) ? $blogs[$day] = array('num' => 1, 'dateline' => $blog['dateline'] - $blog['dateline '] % 86400): $blogs[$day]['num']++;

　}

$cal = '';

　for($row = 0; $row < $rows; $row++) {

$cal .= '';

　for($col = 0; $col < 7; $col++) {

　$cur = $row * 7 + $col - $skip + 1;

　$curtd = $row * 7 + $col < $skip || $cur > $dim ? ' ' : $cur;

　if(!isset($blogs[$cur])) {

$cal .= ''.$curtd.'';

　} else {

　$cal .= ''.$cur.'';

　}

　}

$cal .= '';

　}

return $cal;

　}
